Gee, thanks! :lol:
Have you anything constructive to add to the discussion?
Actually, I think I've already given my .0000002 cents. Should I be alone and suffering from a fatal condition that in no way would impair me during the flight and (brief) sojourn, I would go. The alternative, after all, would be spending my last days on Earth with no real purpose.
Now, I will spare you my philosophical/religious/synthpop views but I firmly believe that there is more to life than just living through it. I wouldn't care if I couldn't be alive to enjoy all the fame and glory and fast women from being the First Man on Mars (OK, I'd miss the fast women), because I'd be too happy to be there, first human on another planet. I would have done something great and scrumptiously cool and that would be enough for me.
However, the conditions for me are clear and since I'm not (fortunately) in those conditions, I cannot volunteer. Now, there are people around who believe an enterprise to be worthy enough to sacrifice their lives to it, so they'd probably go too.
IMHO, the problem is not the volunteer. It's the rest of the team. Could you sit down at the CAPCOM console (no, not the Commando one) and talk for weeks to an end to someone you know will not come back, ever? Could one sustain the emotional pressure to keep watching over someone you know is going to his/her own death, willingly, and you can't change that fact no matter what? As humans, can we bear this kind of ordeal? The person in the ship is going out there to die, and not only there's nothing we can do - we're accessories to this person's death. That's the real question here, if you can find a team who would be mentally and emotionally fit to oversee the mission.
